据英《新科学家》２０００年５月２７日报道 :日本的Ｍａｔ ｓｕｓｈｉｔａ公司发明了一种长寿命灯泡 ,一只５０瓦的灯泡寿命可达６００００小时。现在的灯泡通常是用白炽灯丝发光 ;而荧光灯管则用电极产生的等离子体发光。但这两种类型的灯泡在几千小时后就会烧坏。为了克服这
According to the British “new scientists” reported on May 27, 2000: Japan’s Mat sushita company invented a long-life light bulb, a 50-watt light bulb life of up to 60,000 hours.
